News: Webster was optioned to Triple-A Reno on Monday, Nick Piecoro of the Arizona Republic reports.

Impact: Webster struggled his way through his final spring training outing last Thursday, allowing two earned runs in 1.2 innings. He finished spring training with a 8.18 ERA and 2.09 WHIP with just six strikeouts in 11 innings, and will now begin the season at Triple-A. He remains one of top candidates for a rotation spot, however, if one of the current members were to go down with an injury.

Impact: Webster, who was acquired from Boston in an offseason trade, was 0-1 with an 8.18 ERA in five spring appearances.

News: Webster, who was ejected from his start Monday after beaning Justin Turner, remains in the mix for one of the final spots in the Arizona rotation to begin the season.

Impact: Josh Collmenter, Jeremy Hellickson, and Rubby De La Rosa have been confirmed as members of the rotation, while Chase Anderson is believed to be a part of the group as well. If Anderson's role is confirmed (he's likely the No. 3 starter), Webster, Trevor Cahill, Daniel Hudson, and Robbie Ray appear to be the final candidates for the fifth starter role. Prior to his ejection Monday, Webster allowed two runs on three hits while recording just three outs, lifting his spring ERA to 7.71 over a meager 9.1-innings sample size. Still, he's allowed eight runs on 16 hits -- including two homers, while carrying a mere 6:3 K:BB thus far. Given his performance, and perhaps more importantly, the team's financial investment in Cahill, Webster may be forced to open the season at Triple-A. A decision will likely come down in the final days of spring training.

News: Webster is not a lock for the Diamondbacks' rotation to begin the season, but he may have a leg up on the open competition for one of the final three spots behind Josh Collmenter and Jeremy Hellickson.

Impact: With increased depth, the Diamondbacks should have plenty of competition for rotation spots throughout the season. Webster pitched well in September for the Red Sox to close out 2014, and he'll need to sustain the improved control he showed down the stretch order to keep a starting gig regardless of when that opportunity is afforded him by his new club.
